I can provide my saved game to the developers if they need it, but I think I can describe the problem sufficiently.

I surveyed an anomaly and the reward was that nanobots or some such thing completed the current planetary construction project on a nearby planet. That nearby planet had one thing in its production queue: Aid Research (Repeat). This anomaly reward got in a loop where it would and still will complete Aid Research (Repeat) endlessly. I can choose to end the turn, or remove the production order to end the cycle. Selecting another item on the map for focus puts the loop on pause, but if I re-select the affected planet, I can just keep going back to the Research tree and complete every single technology one after the other all in the same turn.
